Abstract
The invention discloses a method and a device for correcting myopia. A myopia correction desktop which is provided with a flexible limiting support and of which the inclination angle can be adjusted is adopted, and the flexible limiting support is foldable and can limit the eye using distance of the learning; meanwhile, lenses which are provided with far and near visual areas and myopia correction glasses of which the lenses can be conveniently replaced are adopted, eyes look at the front horizontally and the sight looks at a distant place through negative refractive correction areas on upper half parts of the lenses when a user looks at a blackboard or the infinity, and the eyes look down at an inclined downward direction and the sight looks at a near place through zero refraction areas on lower half parts of the lenses when the user looks at books on the desktop so as to avoid the harmful negative refractive correction when the user looks at the near place; the eye using adjustment of an ultrashort distance of the eyes is avoided, and the degree of negative refractive correction lenses is gradually reduced when the eyesight is recovered to a certain degree; and starting from the starting point and direction of changing the aging and recession of a refractive adjustment function of the eyes, the myopia is corrected by utilizing a self-adjustment function of the eyes in the learning process.
Description
Technical field
The present invention relates to a kind of myopia antidote and device, particularly relate to a kind of student and correct in the process of study and prevent bathomorphic method and apparatus.
Background technology
Correction of myopia, is summarized as medical-ophthalmologic problem by traditional understanding, general employing three kinds of modes.
A, wear concavees lens glasses or medical operating optical correction.Utilize the negative dioptric performance of concavees lens, compensate the dioptric value because the less refractive status adapted with it can not be adjusted to when long-term super close distance eye causes crystalline lens and ophthalmic refractive system to see far away, reach with this object seeing blackboard and infinity clearly.The adverse consequences wearing spectacles is, in primary school to senior high school period student, as long as worn spectacles just generally enter the vicious circle that myopia deepens year by year.Medical operating optical correction is the convex rate being reduced cornea eye by modes such as laser surgeys, the refractive power of ophthalmic refractive system is reduced, reaches the raising of distant vision.Problems existing, with concavees lens glasses optical correction method, is not suitable for minor and student, has operation risk.
B, drug therapy orthosis.Be heredity qualitative for myopia or lack the disease of nutrition.The sixties living condition so dispatch a person general malnutritive, few people's myopia, present living condition has been got well, and senior high school period myopia of student incidence reaches about 80% on the contrary.Case can not represent all, simply generally qualitative for myopia be that the diseases such as heredity lack basis, in reality, do not obtain general effective methods for the treatment of and result for the treatment of yet.
C, schooling apparatus orthosis.The myopia corrector of the patent No. [200610067791.5], provide write, reading device and desk and near-sighted glasses with the use of, constantly lower near-sighted glasses number of degrees method myopia correction by control eye Distance geometry.Reality is, only otherwise cancellation band the key factor of the long-time close eye of near-sighted glasses of traditional form, the degree of myopia only can deepen to reduce.The effective usable floor area of portable device of reading and writing is too little can not meet study use, when writing, wrist will raise wrist with the acclivitous angle of clipboard, very uncomfortable, the carefully and neatly done and efficiency that impact is write, volume and weight after folding is not suitable for being placed in school bag, carries and uses inconvenience.Structure is insecure, and slight amount is fragile.
Wear the spectacles of traditional form, compensate the dioptric value because the less refractive status adapted with it can not be adjusted to when long-term super close distance eye causes crystalline lens and ophthalmic refractive system to see far away, myopia can be made to obtain seeing blackboard and infinity clearly, but being applied with harmful concavees lens to eyes equally when seeing near compensate.In the long-term close eye stage of primary school to senior middle school, in original the seeing of maintenance, nearly eye distance is under permanence condition, the consequence that refraction compensation born by the concavees lens harmful to myopia applying is, eyes need the positive dioptric value adjustment increased in contrast to bear dioptric value for offsetting the concavees lens newly increased, just can see clearly be originally accustomed to see nearly eye distance from, after eyes progressively adapt to the spectacles number of degrees newly increased, see that near refractive modulability has increased the refractive modulability with the near-sighted glasses number of degrees equivalent newly increased, see that the corresponding equivalent of regulating power far away lowers simultaneously, in order to compensate be deteriorated again see refractive modulability far away, obtain the clear vision seeing blackboard and infinity clearly, the number of degrees of concavees lens correcting spectacle lens can only be increased again, so cause vicious circle, myopic degree is deepened year by year.From the result that things develops, wearing conventional myopic glasses is under certain conditions incubators that myopia is deepened year by year.The visual range of myopia soon far and between seeing closely is much smaller than normal eyes, have a strong impact on study, work, but myopia soon far away and when seeing near crystalline lens minimum Diopter accommodation state consistent with the adjustable range (refractive power adjustable range) between maximum Diopter accommodation state and normal eyes, difference is between the two the skew in adjustable range or interval.Diopter accommodation during owing to seeing near is far longer than sees that Diopter accommodation far away (need increase Diopter accommodation 3.5D when such as sighting distance is reduced to seen 28cm distance by infinity, need equally when reducing to 14cm by 28cm to increase Diopter accommodation 3.5D, and when reducing to 7cm by 14cm, need to increase Diopter accommodation 7D, need when reducing to 3.5cm by 7cm to increase Diopter accommodation 14D, sighting distance often reduces half Diopter accommodation and must double), this is that convex lens imaging principle determines, so myopia be more suitable for seeing closely be not suitable for seeing far away, normal eyes be suitable for seeing far be not suitable for seeing near.
Normal eyes refractive modulability increases with the age and goes down, and gradates as presbyopia.See near when 10 years old and see that Diopter accommodation scope far away is about 14D; Go down to about 10D when 20 years old; Go down to about 4.5D when 40 years old; Within 75 years old, go down to 0D later.The mode that myopia refractive modulability goes down is contrary with normal person, show and visible sensation distance is, the mode of normal person's eyes visual deterioration is that starting point develops to far point by near point, finally be retained in far point, the mode of myopia decline is that starting point develops near point from far point, is finally retained near point.The reason changing ophthalmic refractive regulatory function decline mode be with eye distance from, with near then useless far away, with far away then useless near.The super close distance eye of some strength cause eyes to be seen nearly Diopter accommodation function is strengthened, see that Diopter accommodation function far away synchronously fails accordingly simultaneously.From the angle of deterioration, myopia and presbyopia do not have difference in essence, just the difference of the form of expression.Myopia is not disease, is that the optics of the initiative that eyes occur long-term super close distance eye regulates change.
The content of invention
The technical problem to be solved in the present invention walks out the mistaken ideas that myopia is disease; According to the process of occurrence and devlopment of myopia and factor, to disclose bathomorphic essence be eyes is adapt to the normal optical that super close distance eye condition occurs regulate and change, and wearing traditional spectacles is the incubators causing myopia to be deepened gradually; There is provided a kind of correct in the process of study and prevent bathomorphic method and apparatus.
For solving the problems of the technologies described above, the present invention by the following technical solutions.
